I found a similar question. But mine is regarding with Messaging Services. As you see the total data used is about 4.5GB. 4GB of them is used in recent two months. The Messaging Services is using about 2.4GB. I want to know why and how to disable Messaging Services because my phone is running in a private 4G network and we never use iMessage or Text Message etc.

    "private 4G network"? You mean one that isn't connected to the rest of the world? – Tetsujin Jan 3 '19 at 8:07

    What are you sending? Video? Pictures? Do you have lots of attachments? – Allan Jan 3 '19 at 13:43
  • Time & Location using 1.3 GB? That’s a little odd, too. – IconDaemon Jan 3 '19 at 23:14
  • @IconDaemon Because I turned on real time location tracking even when app is in background. – Bagusflyer Jan 4 '19 at 1:37
  • @Allan I didn't do anything. Only one application is running which is monitor the location change. – Bagusflyer Jan 4 '19 at 1:39

First, you can check iMessage apps that appear in App tray in Messages (or look for a button with App Store logo beside the text field).
Are there any? If yes, you must check them.
Second, if you say that you "never use iMessage", you can turn it off in Settings.

  • Actually iMessage is turned off. That's why I don't understand why Messaging Services took so much data. – Bagusflyer Jan 4 '19 at 1:47
  • My guess would have been that it's 'wasting data' trying repeatedly to connect to a service it cannot reach - but idk how that would apply if it's switched off entirely. – Tetsujin Jan 4 '19 at 12:05
  • MMS Messaging also? – Andra Jan 4 '19 at 20:04
